Auto light correction: If room lighting isn’t just right, your
video image may be cast in shadows or look washed out.
Auto light correction instantly detects and corrects for poor
lighting. Better webcams have low-light boost, color boost
and adjust exposure so you look your best, even in dim
and harsh lighting.
Face tracking: High-quality webcams can intelligently adjust
framing, keeping your face in the center of the screen when
you move. Some also offer a wide-field-of-view, ideal for
situations when two or more people are on camera.
Sound-enhancing mics: Most webcams have a built-in
microphone. Quality varies. A premium mic will include noise-
reduction technology. High-end webcams come with dual
mics, giving you HD quality stereo audio.
Easy set-up: Webcam setup is simple, much like setting up
a new printer. Insert the webcam’s software CD into your
computer and follow the on-screen prompts. When installa-
tion is complete, plug the camera’s USB cord into your
computer and you’re done.
Video calling software options:
You and the person you’re calling can
make video calls using any webcam and
Instant Messaging (IM) application such
as Skype or Windows Live Messenger.
Download IM software directly from the
web. For the easiest video calling, look
for webcams that come complete with
dedicated video calling software.
PC vs. Mac compatibility: To access all the features of a
webcam, be sure to choose one designed to work with your
operating system. Most webcams are for Windows-based
PCs. Some are designed specifically for Mac. PC webcams
with UVC (USB video device class) compatibility will also
support Mac, although some features may not work.
What to look for
Highest possible video resolution: Video resolution is
the number of dots or pixels captured in an image. The
higher the resolution, the more detail that’s captured,
resulting in more brilliance. The differences in resolution
are considerable:
• Typical built-in webcams: 640x480 pixels in standard
4:3 format
• HD 720p external webcams: 1280x720 pixels in 16:9
widescreen format
• Full HD 1080p external webcams: 1920x1080 pixels
in 16:9 widescreen format
Most fluid HD 720p video calls: The more video frames
per second (fps), the more fluid the video motion.
Conversely, the lower the fps, the more likely you’ll see
strange things like video out of sync with audio or jerky
head movements. Best-in-class webcams consistently
deliver at least 25 fps for HD 720p video calls.
Professional-grade optics: Image quality is only as
good as the lens that captures the image. High-quality
multi-element lenses correct focal and color inaccura-
cies that cause blurry or poorly color-tuned images.
Webcams that use professional optics, such as Carl
Zeiss lenses, give you greatly improved image quality.
Precision focus: Select from three levels of focusing
systems, depending on how little or how much adjusting
you’re willing to do:
• Manual: Lets you adjust focus by hand.
• Fixed Focused/Always Focused: The camera is pre-set
to a specific focus range. Better webcams keep you in
focus by setting the range at 40 cm and beyond, the
typical distance between you and your computer.
• Autofocus: The best webcams focus in and out
automatically. Top-of-the-line models are designed
with precision autofocus that’s ultra-smooth.
Why upgrade to an HD webcam?
The difference in video quality between a regular TV and HDTV is significant. HD webcams
offer this same level of improvement over typical built-in and external webcams.
Using an HD webcam, you’ll immediately notice:
• Richer, true-to-life colors
• Greater image clarity and detail
• Good lighting even in dim and harsh lighting with intelligent auto light correction
• Clearer sound with high-quality built-in microphones
